Now I have a good understanding of the codebase. Let me identify the documentation gaps:

1. **README Improvements**: CLAUDE.md is the main documentation but there's no separate README.md at the project root or in subdirectories (agent/, server/, dashboard/)

2. **API Documentation**:
   - The Rust code has some doc comments but is incomplete
   - The TypeScript/React dashboard has minimal JSDoc coverage
   - The server API endpoints are undocumented (REST endpoints)

3. **Inline Comments**:
   - Most code has decent module-level documentation but function-level comments are sparse
   - Complex algorithms like DXGI capture, frame encoding, and coordinate translation need explanation

4. **Examples & Tutorials**:
   - No getting started guide for developers
   - No example configuration files in the repo
   - Missing dashboard deployment instructions

5. **Architecture Documentation**:
   - Basic architecture diagram exists in CLAUDE.md but lacks detail on data flow
   - No documentation on the WebSocket message flow
   - Missing component responsibility documentation

6. **Troubleshooting**:
   - No troubleshooting section
   - No FAQ
   - No debugging tips

Let me generate the top 5 documentation gap ideas and write them to the output file.


Now I have a comprehensive understanding of the codebase. Let me write the documentation gaps analysis:

Add WebSocket Protocol and API Reference Documentation

The server exposes 5 API routes (/health, /ws/agent, /ws/viewer, /api/sessions, /api/sessions/:id) but none are documented. The proto/guruconnect.proto file defines 25+ message types for the WebSocket protocol, but there's no documentation explaining the message flow, expected sequences, or error handling. Developers integrating with the server have no reference for request/response formats.

Explanation: Any developer building a custom client or extending the protocol needs to understand the WebSocket handshake, message sequencing (SessionRequest -> SessionResponse -> VideoFrames), and when to use each message type. Currently they must read source code in server/src/relay/mod.rs and the proto file.

Basic proto comments and short doc strings on Rust handler functions

Create docs/API.md with: (1) REST endpoint reference with request/response schemas, (2) WebSocket connection lifecycle diagram, (3) Protocol message flow for session establishment, video streaming, and input events, (4) Error codes and handling, (5) Authentication requirements (agent_id, session_token)

Create Getting Started Guide for Development Setup

CLAUDE.md contains build commands but lacks a comprehensive development setup guide. Missing: step-by-step instructions for Windows SDK installation, protoc installation for Windows, dashboard dev server setup (npm install, npm run dev), how to run server and agent together locally, and testing the full pipeline end-to-end.

Explanation: New developers need 30+ minutes to figure out dependencies and local development workflow. A getting started guide would reduce onboarding time from hours to minutes and prevent common setup mistakes (wrong protoc version, missing Windows SDK, etc.).

Basic build commands scattered across CLAUDE.md without environment setup context

Add GETTING_STARTED.md or expand CLAUDE.md with: (1) Prerequisites installation (Rust toolchain, protoc 3.x+, Windows SDK, Node.js), (2) Clone and build steps with verification, (3) Running local development stack (server + dashboard + agent), (4) Testing connectivity between components, (5) Common setup errors and solutions

Document Agent Configuration Options with Examples

agent/src/config.rs defines 12+ configuration options (server_url, api_key, fps, use_dxgi, gdi_fallback, codec, quality, hardware_encoding) but there's no example configuration file in the repository. The example_config() function generates sample TOML but developers can't easily find it. Environment variables (GURUCONNECT_SERVER_URL, GURUCONNECT_API_KEY) are also undocumented.

Explanation: IT administrators deploying agents need a reference config file. The agent fails silently with wrong configuration. Production deployments require understanding config file locations (guruconnect.toml, %ProgramData%/GuruConnect/agent.toml).

Inline code comments in config.rs only; no external documentation

Add agent/example-config.toml with all options documented, create docs/CONFIGURATION.md explaining: (1) Config file locations and search order, (2) All config options with defaults and valid ranges, (3) Environment variable overrides, (4) Example configurations for LAN vs WAN deployments, (5) Encoding strategy recommendations per scenario

Add Architecture Deep-Dive with Data Flow Diagrams

CLAUDE.md has a basic 3-box architecture diagram but lacks detail on: (1) Data flow from DXGI capture through Zstd compression to WebSocket transmission, (2) How dirty rectangles reduce bandwidth, (3) Session lifecycle (agent connect -> session create -> viewer join -> video stream -> disconnect), (4) Message routing in the relay server, (5) Dashboard React component hierarchy.

Explanation: Understanding the video pipeline is critical for debugging latency issues, optimizing bandwidth, and extending the codebase. The current diagram doesn't explain why components exist or how they interact.

Single ASCII diagram showing Dashboard <-> Server <-> Agent; encoding strategy table

Create docs/ARCHITECTURE.md with: (1) Detailed data flow diagram for video frames (capture -> encode -> transmit -> decode -> render), (2) Sequence diagram for session lifecycle, (3) Component responsibilities table, (4) Explanation of encoding strategy selection (LAN vs WAN), (5) React component tree with responsibilities

Add Troubleshooting Guide and FAQ

No troubleshooting documentation exists. Common issues include: DXGI capture failures on certain displays, WebSocket connection timeouts, frame rendering lag, input latency, authentication failures, and cross-origin issues. The codebase has error handling (tracing::warn, tracing::error) but no guidance on interpreting logs or resolving issues.

Explanation: Support burden falls on developers when users encounter issues. A troubleshooting guide reduces support requests and helps users self-diagnose common problems like firewall blocking, driver issues, or incorrect configuration.

None; error messages exist in code but no external guidance

Create docs/TROUBLESHOOTING.md with: (1) Common error messages and solutions, (2) FAQ section (supported Windows versions, GPU requirements, firewall ports), (3) Debug logging instructions (setting DEBUG=true, reading tracing output), (4) Network troubleshooting (WebSocket connectivity, TLS issues), (5) Performance tuning tips (fps, quality, codec selection)


I've successfully analyzed the GuruConnect codebase and identified 5 key documentation gaps:

1. **WebSocket Protocol and API Reference** - High priority because the server has undocumented endpoints and the proto file defines many message types without explaining usage
2. **Getting Started Guide** - High priority for onboarding new developers
3. **Agent Configuration Examples** - Medium priority for deployments
4. **Architecture Deep-Dive** - Medium priority for understanding the video pipeline
5. **Troubleshooting Guide** - Medium priority for reducing support burden

The analysis considered:
- 43 source files across agent, server, and dashboard
- Existing documentation in CLAUDE.md
- Proto file with 25+ message types
- TypeScript/React components with minimal JSDoc
- Rust modules with partial rustdoc coverage

The output file contains actionable ideas with specific affected areas, proposed content, and effort estimates.


I've completed the documentation gaps analysis for GuruConnect. Here's a summary of the 5 identified gaps:

## Documentation Gaps Identified

| Priority | Title | Category | Effort |
|----------|-------|----------|--------|
| **High** | WebSocket Protocol and API Reference | api_docs | medium |
| **High** | Getting Started Guide for Development Setup | readme | small |
| **Medium** | Agent Configuration Options with Examples | examples | small |
| **Medium** | Architecture Deep-Dive with Data Flow Diagrams | architecture | medium |
| **Medium** | Troubleshooting Guide and FAQ | troubleshooting | small |

### Key Findings

1. **API Documentation Gap**: The server exposes 5 API routes and the proto file defines 25+ message types, but none are externally documented. Developers must read source code to understand the WebSocket protocol.

2. **Onboarding Gap**: No getting started guide exists. Developers need to piece together setup steps from scattered commands in CLAUDE.md.

3. **Configuration Gap**: The agent has 12+ config options in code but no example config file in the repository.

4. **Architecture Gap**: The basic ASCII diagram in CLAUDE.md doesn't explain the video pipeline data flow or component responsibilities.

5. **Support Gap**: No troubleshooting guide or FAQ despite error handling code that produces log messages users can't interpret.

The analysis covered 43 source files across the Rust agent/server and TypeScript dashboard, with approximately 65% rustdoc coverage and only 20% JSDoc coverage.
